Non-JSON log line "remote error: tls: unknown certificate"

[NorseGaud]

The following are the logs I'm seeing from the prometheus exporter I've built. The last line happens when I launch the landing page/url in my browser. The cert is self-signed so I expect it to maybe warn, but I certainly don't expect it to be non-JSON as I'm passing my logger in and it uses JSON.

	if err := web.ListenAndServe(&http.Server{}, &web.FlagConfig{
		WebListenAddresses: &[]string{server.webListenAddress},
		WebConfigFile:      &server.configFile,
	}, log.Logger); err != nil {
		log.Error(fmt.Sprintf("Error starting web server: %s", err.Error()))
		os.Exit(1)
	}

❯ go run -ldflags="-X main.version=$(cat VERSION) -X main.commit=$(git rev-parse HEAD)" main.go --controller-address http://anka.controller:8090 -web.config.file web.config.yml

2024/09/17 20:43:53 http: TLS handshake error from 127.0.0.1:54574: remote error: tls: unknown certificate

I'm having trouble finding where this comes from though. It seems to be generated from something not using the logger I passed in.

Any recommendations?
